Backup camera, which wires to tap

[RobLO]

Okay, how to wire a Emmako backup camera to my 2019 Jay Feather 25RB. I didn’t use a Furrion as its plug had no power, and if it did it was only with TV lights on.
It is all buttoned up outside just need to a little additional weatherproofing.
I want to wire it to the rear bath fan so I can run the camera as a monitor as well. May add another switch in ceiling next to fan shroud.
The wall switch sends power to the fan and then there is another switch on the fan itself so I can have the fan off but power the camera.
In the photo below I show the wiring for the fan with the black camera wire pulled through to the fan wiring.
I believe the hot white looping wire with the blue tap to the fan is to the wall switch.
I think, but am not 100% sure that I just need to tap, the way Jayco has here, the white to white looping wire and the red to the yellow terminated / tapped to the black switch wire.
Is this correct?
